Marantz PM6005 Integrated Amplifier and CD6005 CD Player


The Design and Setup of the Marantz PM6005 Integrated Amplifier and CD6005 CD Player

The front of the CD6005 includes a power/standby button with an indicator LED and a series of small buttons to control the transport functions. Marantz provides a ¼" headphone jack with a separate level control to allow the use of headphones without the need for turning on the amplifier.

Conveniently included is a USB- Type A input. Although it supports any of several compressed music formats (WMA, MP3, AAC) and WAV files, it does not support FLAC files. I suspect many potential users have at least some portion of their music collection ripped to FLAC, and I for one would have appreciated the inclusion.

The back of the CD6005 includes both a coaxial and an optical SPDIF output as well as a pair of RCA output jacks, enabling one to use either the Marantz' internal DAC or an external DAC. There is also an input for an external IR flasher as well as a remote input and output, allowing the included remote control to also operate a Marantz amp such as the PM6005. This allows the amp to be placed out of sight, such as in a cabinet.

The amplifier front panel features two large knobs, one for controlling the volume and the other for selecting each of the five input sources. LED's indicate the source in use. There are also three smaller knobs to control bass, treble, and balance. Immediately below them are four small buttons to select - Source Direct which bypasses the tone and loudness controls, Speaker buttons to select up to two pairs of speakers, and the Loudness function. Finally there is the Power/Standby button and a ¼" headphone jack which is controlled by the main volume knob.

The rear panel includes five pairs of RCA inputs, one set feeding a moving magnet phono input and a set of stereo RCA outputs to allow connection to a tape deck. There is also a pair of digital SPDIF inputs, one coaxial and one optical, allowing one to utilize the internal DAC with other devices such as media players, CD players, streamers, etc. There are four sets of high quality speaker binding posts, allowing the connection of either two sets of speakers or bi-wiring one set. Rounding out the back side are the external IR flasher input jack and the pair of external remote RCA jacks to be used with the CD6005 as described above. One other feature which I find really useful and absent nowadays on most receivers and many amps is the addition of two switched and one unswitched AC outlets. However, these should not be used to turn on components that draw a lot of current.

The amp has a rated power output of 45 watts into eight ohms and 60 watts into four ohms, with THD+N specified at 0.08% from 20 Hz to 20 kHz. As we shall see later in the review, the rated power was more than adequate, driving real world speakers to very loud listening levels.

The mostly full-featured remote control is the same unit for both the CD player and the amplifier and contains separate Power buttons for the two so that they can be turned on independently, as well as transport buttons to play, pause, stop and skip tracks on the player. Strangely, there is no Eject button on the remote; one must press the button on the front of player to open the tray, although it can be closed by hitting the play button.

Since both the PM6005 and the CD6005 utilize the same Cirrus Logic CS 4398 DAC chips, I just connected the them using the supplied RCA cables rather than a digital connection. I initially listened over a pair of Wharfedale 10.2 speakers sitting on a shallow bookshelf in my home office. I did not use a subwoofer. I also hooked up a Denon DP-300F turntable with an Ortofon 2M Red cartridge using the Marantz' built-in phono preamp. For digital listening, I connected an Acer Netbook, running JRiver Media Center 19 via USB to a Peachtree DAC*IT and then via RCA cables to the Network input on the amp. As noted later in the review, I changed this configuration several times to fully explore the various capabilities of these two components and to try to anticipate how owners might utilize them in various systems, with both analog and digital sources.
